yes, the 'i was unhappy before i shagged around on you'.
then grow a pair and walk out and maybe i'd have a shred of respect for you.
but otherwise? nah.
i was there, too.
my relationship had broken down and i started to grow close to someone i knew.
called a 'talk' one night. most painful one of my life.
told ex h point blank, 'i am starting to think about having sex with other men (we'd been having problems because of an impasse we'd reached about having kids) and i don't know what to do, but i'd rather split than do that.'
so we went to counselling and decides to split.
two years later, we divorced.
and man, it HURT. the moving out, the finding a new place, selling our home, etc.
but ex H is a nice man. he still is (we're still pals and he's also happily remarried and childfree). he didn't deserve someone doing that to him.
